Distribution of the threshold energy E_th and angular scale ψ of the BS maxima obtained after the analysis of 300 datasets assuming the same astrophysical models as in Fig. 2, the JF12+Planck model with λ_c = 200 pc (top panel), and the Sun+Planck model with λ_c = 100 pc (bottom panel). The colour scale represents the fraction of realisations for which the BS maximum is obtained in a given (E_th, ψ) bin.
